Problems solved by technology

Microplastics are mainly concentrated in the most surface water body. Usually, the deeper the concentration, the smaller the concentration. However, the current general-purpose water sample collectors use location and depth as parameters and cannot collect surface water samples well (microplastic-enriched areas )

Abstract

The invention discloses a multi-cavity sampling device for microplastic on surface water. The multi-cavity sampling device comprises a cylindrical net framework, a plurality of filter screen structures, a connecting rod penetrating through inside of the device, a plurality of limiting devices matched with the connecting rod, a leaking box and buoys fixed on two sides of the net framework, whereinmesh size of the plurality of filter screens and the filter screen structures in the device is reduced from top to bottom in sequence. Compared with the prior art, an existing microplastic collectingdevice for the surface water filters and screens microplastic garbage in water only by primary filter screens and cannot separate the microplastic garbage; the device provided by the invention can screen different sizes of microplastic and organic contaminated sphere garbage, the structure is simple, and the design is reasonable.

Description

technical field [0001] The invention relates to the field of marine and water environment science and technology, in particular to a multi-chamber sampling device for surface water microplastics. Background technique [0002] Generally speaking, there are already a wide variety of plastics in life, such as polyethylene, polystyrene, etc. These compounds are exposed to the wind and sun in the natural environment. Although they cannot be completely degraded, they are gradually becoming smaller. , into microplastics smaller than particles. In addition, there are a lot of abrasive particles in the cosmetics or cleaning products we use. These particles are small in size and float on the water surface. The urban sewage treatment plant cannot handle them at all, so they cannot decompose and leave the sewage treatment plant freely. [0003] Plastic waste is mostly stable long-chain polymers, which are not easy to degrade in the natural environment, but can be broken into tiny plast...
